If the hon. Gentleman would listen, he might learn.
It is essential that understanding precedes enjoyment. Enjoyment will involve varying noise levels. What is required is sensible management of the parks, which already exists, with powers to control activities that take place within the boundaries of the parks.
To start with, I was most impressed by my constituents' representations in favour of "quiet enjoyment", but then I started to receive representations from those who use the parks regularly, who pointed out that they take part in all kinds of activities. That includes not only motor sport but model aircraft flying—a nuisance unless it is properly controlled, but if it is properly organised it is an activity that interests young and old, and obviously people can participate in that activity in a national park.
Tonight, we shall not simply take the word "quiet" away from the word "enjoyment" but put in the "understanding" that has to precede enjoyment. That will allow people to enjoy a park and not to abuse it, because they understand the requirements of the area.
